If you want to play Uno free online but don't know the rules, don't worry. You can play a tutorial game, or simply play solo to learn by following the gameplay. It's really a very easy, basic game based on colors, numbers and a few special cards.

The idea is to get rid of all your cards, but the other players will be doing their best to make you miss a turn, pick up more cards or selecting colors and numbers you don't have in your hand. How will they know? Based on times you didn't make a play and had to pick up from the deck, they will remember what you are weakest in and play to that.

As Uno games go, this is a very simple one and tons of fun to play. There is a time limit, but you will see that usually you get to play three hands within the time available. You score based on how many cards the other players had left when you finished. All your scores for each hand are combined to give you a total score.
